In this paper we empirically investigate the temporal development of a firm’s strategy implementation consistency (SIC), i.e. the alignment between firms’ resource allocation decisions (RAD) and their articulated corporate concept (Noda
and Bower, 1996; Burgelman and Grove, 1996; Love et al., 2002; Mintzberg, 1978). Doing so, we test whether (1) SIC is more
likely to increase or decline over time, (2) whether firms competing in (low) high-velocity environments in fact show different
temporal patterns in SIC, and (3) whether overperforming firms succeed in conserving their level of SIC. For our analysis
we draw on 6238 RAD of 20 publicly listed firms with European origin over a period of 4–6 years. Applying maximum likelihood
ordered logit estimation, our results indicate that the likelihood of an alignment of RAD and a firm’s corporate concept decreases
over time. In line with scholars’ perception of high-velocity environments, we find that the firms in our sample competing
under such conditions show no clear trend in SIC. These firms tend to “zig-zag” over time – swaying off and pulling back to
their strategic course independent of the timing of the announcement of a corporate concept. We also find that overperforming
firms are unsuccessful in preserving their SIC at the same level over time. Based on the empirical findings the paper discusses
implications for theory and derives suggestions for corporate level managers on how to balance SIC and strategic flexibility. 相似文献

A large body of literature investigates whether a stable and predictable long-run association between money and its arguments exists. One point of variation between models is whether to include an interest rate measure directly within the long-run relationship. Several recent studies indicate that empirical findings are sensitive to the choice. Therefore, the present article reexamines the empirical significance of the interest rate within a four-equation macroeconomic system. The results suggest that the interest rate (1) may be excluded from the M2 demand function, (2) is strongly exogenous to most of the system's remaining variables, and (3) may represent a common trend. 相似文献

Neuroimaging research has brought major advances to child health and wellbeing. However, because of the vulnerabilities associated with neurological and developmental conditions, the parental need for hope, and the expectation of parents that new medical advances can benefit their child, pediatric neuroimaging research presents significant challenges to the general problem of consent in the context of research involving children. A particular challenge in this domain is created by the presence of therapeutic misconception on the part of parents and other key research stakeholders. This article revierws the concept of therapeutic misconception and its role in pediatric neuroimaging research. It argues that this misconception can compromise consent given by parents for the involvement of their children in research as healthy controls or as persons with neurological and developmental conditions. The article further contends that therapeutic misconception can undermine the research ethics review process for proposed and ongoing neuroimaging studies. Against this backdrop, the article concludes with recommendations for mitigating the effects of therapeutic misconception in pediatric neuroimaging research. 相似文献

We show experimentally that fairness concerns may have a decisive impact on the actual and optimal choice of contracts in a moral hazard context. Bonus contracts that offer a voluntary and unenforceable bonus for satisfactory performance provide powerful incentives and are superior to explicit incentive contracts when there are some fair‐minded players, but trust contracts that pay a generous wage up front are less efficient than incentive contracts. The principals understand this and predominantly choose the bonus contracts. These results are consistent with recently developed theories of fairness, which offer important new insights into the interaction of contract choices, fairness, and incentives. 相似文献

Norovirus Dose–Response: Are Currently Available Data Informative Enough to Determine How Susceptible Humans Are to Infection from a Single Virus?

Two forms of single‐hit infection dose‐response models have previously been developed to assess available data from human feeding trials and estimate the norovirus dose‐response relationship. The mechanistic interpretations of these models include strong assumptions that warrant reconsideration: the first study includes an implicit assumption that there is no immunity to Norwalk virus among the specific study population, while the recent second study includes assumptions that such immunity could exist and that the nonimmune have no defensive barriers to prevent infection from exposure to just one virus. Both models addressed unmeasured virus aggregation in administered doses. In this work, the available data are reanalyzed using a generalization of the first model to explore these previous assumptions. It was hypothesized that concurrent estimation of an unmeasured degree of virus aggregation and important dose‐response parameters could lead to structural nonidentifiability of the model (i.e., that a diverse range of alternative mechanistic interpretations yield the same optimal fit), and this is demonstrated using the profile likelihood approach and by algebraic proof. It is also demonstrated that omission of an immunity parameter can artificially inflate the estimated degree of aggregation and falsely suggest high susceptibility among the nonimmune. The currently available data support the assumption of immunity within the specific study population, but provide only weak information about the degree of aggregation and susceptibility among the nonimmune. The probability of infection at low and moderate doses may be much lower than previously asserted, but more data from strategically designed dose‐response experiments are needed to provide adequate information. 相似文献

Technology-based spin-offs from academic institutions and private corporations represent an important proportion of young innovation-oriented ventures. They encounter specific starting conditions in terms of their core technology, the composition of the founding team, and the critical junctures during their establishment. This study analyses the state-of-the-art in quantitative empirical research on factors impacting the development of these types of firms. We present findings of both research fields and discuss them critically. Methodological and measurement issues receive particular attention in our analysis. Based on the literature review we identify factors impacting the development of both types of firms. Additionally we expose gaps in past and current research on academic and corporate spin-offs and suggest interesting opportunities for future research. Methodological shortcomings of existing studies are discussed. We derive implications for research on academic and corporate spin-offs and for the management of these types of firms. 相似文献

Common ratio effects should be ruled out if subjects’ preferences satisfy compound independence, reduction of compound lotteries, and coalescing. In other words, at least one of these axioms should be violated in order to generate a common ratio effect. Relying on a simple experiment, we investigate which failure of these axioms is concomitant with the empirical observation of common ratio effects. We observe that compound independence and reduction of compound lotteries hold, whereas coalescing is systematically violated. This result provides support for theories which explain the common ratio effect by violations of coalescing (i.e., configural weight theory) instead of violations of compound independence (i.e., rank-dependent utility or cumulative prospect theory). 相似文献

This research investigates how information asymmetry between the firm and its investors can influence supply chain disruptions. In such settings, these actors may be induced to take steps which exacerbate rather than ameliorate both the likelihood and impact of disruptions. By better understanding these mechanisms, managers and investors alike are better armed to avoid the costly consequences. 相似文献
